Nonlinear hydroelastic FSI model for stability analysis of foam sandwich beams under viscous water flow

Journal of Ocean Engineering and Science
Within the framework of an equivalent single-layer beam theory incorporating moderately large deformations at contact surface, a nonlinear hydroelastic fluid-structure interaction (FSI) model is developed to investigate the buckling and postbuckling ...
